Galois action

Roots of defining polynomial

The roots of $f$ are computed in an extension of $\Q_{ 353 }$ to precision 5.

Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 353 }$: $ x^{2} + 348 x + 3 $

Roots:

$r_{ 1 }$	$=$	$ 306 + 81\cdot 353 + 153\cdot 353^{2} + 289\cdot 353^{3} + 13\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 124 a + 13 + \left(4 a + 102\right)\cdot 353 + \left(266 a + 141\right)\cdot 353^{2} + \left(139 a + 292\right)\cdot 353^{3} + \left(10 a + 341\right)\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 318 a + 298 + \left(37 a + 330\right)\cdot 353 + 301\cdot 353^{2} + \left(189 a + 227\right)\cdot 353^{3} + \left(22 a + 271\right)\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 86 + 238\cdot 353 + 103\cdot 353^{2} + 195\cdot 353^{3} + 26\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 5 }$	$=$	$ 229 a + 280 + \left(348 a + 352\right)\cdot 353 + \left(86 a + 54\right)\cdot 353^{2} + \left(213 a + 19\right)\cdot 353^{3} + \left(342 a + 254\right)\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 6 }$	$=$	$ 307 + 103\cdot 353 + 39\cdot 353^{2} + 274\cdot 353^{3} + 308\cdot 353^{4} +O\left(353^{ 5 }\right)$
$r_{ 7 }$	$=$	$ 35 a + 123 + \left(315 a + 202\right)\cdot 353 + \left(352 a + 264\right)\cdot 353^{2} + \left(163 a + 113\right)\cdot 353^{3} + \left(330 a + 195\right)\cdot 353^{4} +O\left(353^{ 5 }\right)$
